How common are planetary systems?
My research group is interested in the prevalence of planetary systems orbiting other stars and how the properties of those planets depend on the characteristics of the host star. We tend to concentrate on stars known as "M Dwarfs." These stars, also dubbed "Red Dwarfs," are significantly smaller than the Sun and are the most common type of star in the galaxy. Exploring the properties of planetary systems orbiting M dwarfs allows us to estimate the overall frequency of planetary systems and test models of planet formation.
